Análisis del desgaste de la zona de peligro por la conformación del conducto radicular, revisión bibliográfica.

Abstract

Objective: To analyze the wear and tear of the danger zone by the formation of the root canal. Materials and methods: Literature review study, with a qualitative approach of transversal type, with a type of descriptive and retrospective investigation, for the obtaining of data documents of a time interval between 1992 - 2020 were used. Results: Dentine wear in millimeters with rotating instruments and root canal transport, the mechanized system Hyflex EDM, with 0.42 mm dentine wear, caused less root canal transport. The mechanized system that caused more dentine wear and root canal transport was K3XF with 0.83 mm; while, cervical dentine removal in millimeters by instruments for coronal preparation, the Profile system, had less wear, on average 0. 43 mm of cervical dentin, while the Hyflex EDM system had the highest wear, on average 1.91 mm; as for the prognosis/failure of endodontic treatment, the accessory canals had a value of 2.6 %, the lowest cause and the highest cause of prognosis or failure of endodontic treatment was periodontal disease with 40.30 %. Conclusion: Danger zones are areas that require interest on the part of the clinician in order to be successful in endodontic therapy. The skill and experience of the clinician in relation to the anatomical diversity of the teeth to be treated is another factor in determining the success or failure of endodontic treatment.
